Rumors of an apparent Jenna Jameson pregnancy have been swirling for weeks now -- so it's interesting that she is tackling the issue of birth control -- for pets!

In a new PETA ad campaign to promote the spaying and neutering of cats and dogs, the porn princess will appear nude in bed, with the tagline, "Sometimes Too Much Sex Can Be a Bad Thing."

The always eloquent Jenna stated, "Until dogs and cats can go on the pill or wear condoms, we need to help them practice safe sex -- by spaying and neutering."
